Can i set an automatic opening and closing time to my shop?

Good question. We don't currently support an automatic feature for turning your store on and off - which I believe is what you're after here? We do have a maintenance mode feature available from the "advanced" settings page, and you can enable that to turn off the checkout, preventing anyone from being able to complete a checkout. You can also edit the message they see from the "langauge" section of the admin.

If you wanted to automate it, you could utilise our API to toggle the maintenance feature on and off with a custom script set up on your side. Our API allows you to manage all aspects of your store - anything you can do in the admin you can do through the API.
